Rat body positioning device for tail intravenous injection in rats

Abstract

The invention discloses a rat body positioning device for tail intravenous injection in rats. The positioning device includes an accommodation platform; the end surface of the accommodation platform is provided with an accommodation groove; an accommodation plate is rotatably arranged in the accommodation groove; the accommodation plate is connected to the inner wall of the accommodation groove through a rotating shaft, and the rotating shaft is rotatably arranged on the inner wall of the accommodation groove; the upper cover of the accommodation plate is provided with a clamping plate; multiple colliding blocks are uniformly arranged on the side, facing toward to the accommodation plate, of the clamping plate; open grooves are arranged in the end surfaces on the ends, facing toward to theaccommodation plate, of the multiple colliding blocks, and are arranged along the length directions of the colliding blocks; extrusion blocks are slidingly arranged in the open grooves, and resettingmembers are also arranged in the open grooves; a limit member is arranged in the accommodation groove; and the accommodation plate is provided with a fixing member and a clamping member. Thus, the problems in the prior art of failed intravenous injection caused by body twisting during the injection of rats due to unstable fixation of the rats can be solved.

Description

technical field [0001] The invention relates to the technical field of rat auxiliary fixation devices, in particular to a rat body positioner for tail vein injection of rats. Background technique [0002] In existing laboratories, it is usually necessary to inject various drugs into rats, among which intravenous injection of rats is particularly important. However, before intravenous injection of rats, experimenters usually need to pass rat limbs through parts such as rubber bands or elastic bands. Fix it on the experimental table to ensure that the rat will not fail the experiment due to twisting or crawling during the experimental injection process, and then the operator turns his head and injects the vein on the left or right side of the rat tail through the injection device. In the prior art, the firmness of the elastic band or the rubber band is too poor, and because of its good elasticity, the rat can still swing in the test bench. If the rat twists the body or the but...

Problems solved by technology

[0003] Aiming at the deficiencies of the prior art, the present invention provides a rat body positioner for intravenous injection of the rat tail, in order to solve the problem that the rat is unstable in the prior art, so that the rat's body twists during the injection process and leads to intravenous injection. failure problem
